| Outline of Final Research Achievements |
Clinical samples such as paraffin blocks for histopathological diagnosis of tuberculosis about several decades ago (1960s to 1970s) were challenged to purify DNA of the etiological agent, Mycobacterium tuberculosis. Phylogenetic classification of these samples reveals that unique population genetic structure of M. tuberculosis in Japan has been already seen. A genetic group B2, which was considered to have spread for several hundred years from genomic comparative analysis, was also found frequently in the old samples. The DNA analysis techniques to target on mycobacterial DNA are applicable to clinical diagnosis for mycobacterial infection such as extra pulmonary tuberculosis and veterinary cases.
